Richard Attenborough stars in this British drama as Tom Curtis, an ordinary man with a job in a factory. A new employee, Travers (Alfred Burke), begins complaining about conditions at the plant and stirs up disharmony among his fellow workers.
Tom thinks that there's something fishy about Travers and his methods, and when Travers decides to call a wildcat strike, Tom refuses to participate and makes a point of standing his ground.
However, Travers and his ideas have attracted a groundswell of support in the factory, and Tom soon finds himself on the outs with his fellow employees as Travers drifts off to make trouble at another factory.
Tom, however, still has to deal with the angry reprisals of the men, and his wife Anna (Pier Angeli) doesn't understand why he continues to hold so unpopular an opinion at the expense of his safety and well-being.
